Vulnerability (status effect)
|Your willpower is weaker, making you vulnerable to many magical effects.|
Vulnerability (displayed as Will/2) is a status effect which temporarily halves the willpower of its victim, making them more susceptible to many Hexes and similar effects. Although player-available sources of it are rare, hexers can make good use of it to aid in disabling certain strong-willed opponents. Just be aware that monsters with exceptionally strong will may still be fairly resistant afterwards, and that opponents with unshakeable will are entirely unaffected.
